How to Delete Multiple Contacts on iPhone is straightforward once you use the current iPhone controls. The exact wording can vary slightly by iOS version, carrier, and iPhone model.
- Open Contacts.
- In the contacts list, use two fingers to touch and hold a contact, then drag up or down to select adjacent contacts.
- Touch and hold the selected contacts.
- Tap Delete Contacts and confirm.
If the contacts are synced from an online account, deleting them can also remove them from other devices using that account.
Before making the change, make sure the iPhone is running a current iOS release and that you know any passcode, Apple Account, carrier, or app credentials the feature may require. If the labels on your screen do not exactly match these steps, use Settings search to find the named feature rather than choosing a similarly named control. Apple occasionally moves settings between iOS releases.
